Letters Patent N 106,696, dated August 23, 1870.

IMPROVEMENT IN BLOTTING-PADS.

The Schedule referred to in these Letters Patent and making part of the same.

To all to whom these presenls'mny come:

Be it known that I, GEORGE O. HtSuAmof Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful or improved Blotting-Pad; and I do hereby dcclarethc same to be fully described in the following specification, and represented in thc accompanyingdrawing, of which Figure 1 denotes a top view, and

Fignre'iZ, a side elevation of a blotting-pad,constrncted in accordance with my invention.

My invention relates to that class of devices de;

signed to remove the surplus ink from a paper which has been written upon, in order to prevent any smoochiug or blotting of such paper; and

, My invention consists in making the body or metallic portion of the device of a single steel or metallic plate bent or curved longitudinally into the form of an ellipse, which, when enveloped by one or more sheets of blotting-paper, or absorbent material, shall form a blotting-surface upon each of its two sides.

In thc'said drawing---- A denotes the body or frame of the device, the same consisting, ofa steel or metallic plate, having its two ends bent around, and brought into contact, so as tod'orm clamping-jaws a a.

The form of the said frame or body is that of an I ellipse, or a figure closely approximating thereto. By thus making the said frame of a singl metallic plate, and giving'it the form described, such not only serves to cushion or give elasticity to the pad, but it enables each of its two sides to he used with equal facility The common blotting-pad has but a single blottingsurtace, its opposite side or face being provided with aknob or handle. This I entirely dispense with, and

thus make the pad a duplex or double-faced one.

.Theiramc or body-portion made in my improved manner is to have one or more bands or strips, 0, of

blotting or absorbent paper, applied to its outer surface, such paper being of a width corresponding with that of the metallic frame, and of a lengt-lr'a little greater than the perimeter of the said frame, in orderthat theends ot'thc paper maybe extended between and beyond the jaws a a, by which they are clam pod and'held firmly in position.

By my construction of the said body-portion with the cla|npiugjaws, arranged as described, and the blotting-paper applied thereto, as set forth, when one surface of such paper becomes worn or saturated with ink, we have simply to release one end thereof from the jaws and turn it back over the opposite side of the wherein I also obtain two blotting-suriitces, but the device is more complicated, without offering any additional feature of utility over that shown in the other figures.

My invention is not only simple in construction and eflioient .in operation, but can be made at small cost, and is not liable to get out of repair.

In using it, we simply grasp it between th thumb and fingers of one hand, and rock it back and forth over the inked surface to be operated on.

Having thus'described my invention,

What I claim is as follows:

A duplex or double-face blotting-pad; substantially as described and shown, and for the purpose set forth.

G. O. HINMAN.
